Anatomy of the Global Saving Glut

Anatomy of the Global Saving Glut

 

In this paper, Luis Bauluz, Filip Novokmet and Moritz Schularick provide a distributional perspective on global saving and wealth accumulation since the 1980s. They calculate saving flows and capital gains across the wealth distribution for the G3 economies – the U.S., Europe, and China. This allows them to identify which households shaped the “Global Saving Glut”, finding a marked increase in saving by the global rich (driven by corporate saving) and a decline for the middle classes.  All else equal, in the absence of significant capital gains in housing, the rising inequality of savings would have led to a significantly higher concentration of wealth.

 

4 key findings

 

  • The years 1980 to 2018 witnessed a marked increase in the inequality of household saving in all G3 economies: around 1980 the top-10% accounted for around 60% of all household saving rising to about 90% in 2018.
  • The most important source for the surge in top-10% saving was the secular rise of global corporate saving whose ultimate owners are the rich households.
  • Saving flows played the key role for wealth accumulation of the top-10% and capital gains in housing for middle-class households across the G3 economies.
  • Without meaningful saving or capital gains, the wealth share of the bottom half of the population declined in most G3 economies.

Anatomy of the Global Saving Glut

 

This figure shows the development of the G3 top 10%, bottom 90% and government saving. G3 (U.S., China and Europe) saving is the combination of top 10%, bottom 90% and government saving in the U.S., China and Europe. G3 saving is scaled by G3 national income. Cross-country combinations use market exchange rates to convert local currencies into US dollars. Series are 5-year moving averages.
